Relationship between Coolant Concentration and Specific Gravity
CAUTION
• If the concentration of the coolant is below 30%, the anti-corrosion property will be adversely
affected. In addition, if the concentration is above 60%, both the anti-freeze and engine cooling
properties will decrease, affecting the engine adversely. For these reasons, be sure to maintain
the concentration level within the specified range.
